Look of the Week: November 15, 2012Olivia Wilde wore Dolce & Gabbana to the Museum of Natural History Gala in New York City.

Olivia Palermo is one of those girls who has the art of high-low mixing down pat. A couture dress with Zara heels? Just another day in the life of one of New York's most enviable fashionistas.

Though normally Olivia sports multiple designers per outfit, she showed up to the Christian Dior Haute Couture show in Paris wearing head-to-toe Dior. A crisp white blazer was nipped at the waist with a b-e-a-utiful embellished belt, and worn over an iridescent purple organza skirt. Single sole, pointy toe pumps completed the look.

We're so obsessed with this gorgeous look that we're going to let Olivia off the hook for not sticking with her usual mix of ultra-luxe designer labels and affordable fast fashion just this once. After all, when at the Dior Haute Couture show, it would be rude not to wear Dior!
